Answer:
Percentage error is 39.39%
Step-by-step explanation:
It is given that,
The calculated value that Erika spend on school supplies this year is $115.
Actual value that she spent is $82.50.
We need to find Erika's percent of error. Percentage error is given by the formula as follows :
[tex]\%=\dfrac{\text{calculated value}-\text{actual value}}{\text{actual value}}\times 100\\\\\%=\dfrac{115-82.5}{82.5}\times 100\\\\\%=39.39\%[/tex]
So, Erika's percent of error is 39.39%.
